It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more.

Fig. 1 is a flow chart of a method for improving quality of a transmission signal according to an embodiment of the present application. The transmission signal quality improving method may include:
step 101: acquiring first signal quality of a transmitting signal of a first antenna and second signal quality of a transmitting signal of a second antenna, wherein the first antenna is an antenna before antenna switching, and the second antenna is an antenna after antenna switching;

step 104: the impedance of the second antenna is tuned according to the first load impedance and the target load impedance to improve the quality of the transmitted signal.
The specific implementation of each of the above steps will be described in detail below.
In the embodiment of the application, the signal quality of the transmitted signal before antenna switching and the signal quality of the transmitted signal after antenna switching are obtained; under the condition that the signal quality of the transmission signal after antenna switching is smaller than that before antenna switching, the forward power and the load reflected power of the power amplifier are obtained; determining a first load impedance of the power amplifier based on the forward power and the load reflected power; and tuning the impedance of the antenna after antenna switching according to the first load impedance and the target load impedance. Thus, the signal quality of the transmission signal can be improved, and the signal quality degradation of the transmission signal can be avoided.
It will be appreciated that the first signal quality in the embodiments of the present application is the quality of the signal transmitted through the first antenna, and the second signal quality is the quality of the signal transmitted through the second antenna.
Fig. 2 is a schematic structural diagram of a transmission signal quality improvement system according to an embodiment of the present application. The transmission signal quality improvement system may include a Modem (Modem) 21, a Transceiver (transmitter) 22, a Power Amplifier (PA) 23, a Coupler (Coupler) 24, a double pole double throw switch (Double Pole Double Throw, DPDT) 25, and two antennas 26, and two tuners (tuners) 27 corresponding to the two antennas 26.
In some possible implementations of the embodiments of the present application, whether the antenna switching condition is satisfied may be determined by an antenna switching diversity (Antenna Switching Diversity, ASDiv) algorithm, and when the antenna switching condition is satisfied, antenna switching is implemented by controlling the DPDT. The embodiment of the present application is not limited to the manner of determining whether the antenna switching condition is satisfied by the ASDiv algorithm, and any available manner may be applied to the embodiment of the present application. For example, the determination is made by reference signal received power (Reference Signal Received Power, RSRP), maximum transmit power limit (Maximum TX Power Limit, MTPL), power margin value (Value of Power headroom, VPH), etc.
In some possible implementations of embodiments of the present application, in step 101, the signal quality of the transmitted signal before and after antenna switching may be detected by a feedback reception (FBRx) feedback path. Specifically, the FBRx signal may be demodulated by the radio transceiver 22 and the modem 21 to obtain the signal quality of the transmission signal.
In some possible implementations of the embodiments of the present application, when the second signal quality is less than the first signal quality, it indicates that the signal quality of the transmission signal is degraded after the antenna is switched, and it is desirable to improve the signal quality of the transmission signal.
In some possible implementations of the embodiments of the present application, in step 102, the forward power and the load reflected power of the power amplifier may be detected by the coupler 24, to obtain the forward power and the load reflected power of the power amplifier.
In some possible implementations of embodiments of the application, step 102 may include: and under the condition that the difference value between the first signal quality and the second signal quality is larger than the signal quality difference value threshold value, acquiring the forward power of the power amplifier and the load reflected power. The signal quality difference threshold may be set according to actual requirements.
When the difference between the first signal quality and the second signal quality is greater than the signal quality difference threshold, it indicates that the signal quality of the transmitted signal is seriously degraded after the antenna is switched, and the signal quality of the transmitted signal needs to be improved.
In some possible implementations of embodiments of the application, step 103 may include: determining a load reflection coefficient according to the forward power and the load reflection power; the first load impedance is determined based on the load reflection coefficient.
In some possible implementations of embodiments of the present application, determining the load reflection coefficient from the forward power and the load reflected power may include: the load reflection coefficient is determined according to the following formula (1):
wherein in formula (1)Wherein, Γ L For load reflection coefficient, P forward For forward power, P reverse Reflecting power for the load.
In some possible implementations of the embodiments of the present application, determining the first load impedance according to the load reflection coefficient may include:
determining a first load impedance according to the following equation (2):
wherein in the formula (2), Z load For the first load impedance Γ L Is the load reflection coefficient.
In some possible implementations of the embodiments of the present application, different Load impedances may be traversed in advance by a Load-pull test to obtain a Load impedance Z that enables the signal quality of the transmitted signal to reach the target signal quality optimm (i.e., target load impedance). The target signal quality in the embodiment of the application is the signal quality which can be achieved by the maximum signal quality of the transmitting signal.
In some possible implementations of embodiments of the application, when Z optimm Greater than Z load When the load impedance of the power amplifier needs to be increased, namely the impedance of the second antenna is increased; when Z is optimm Greater than Z load When the load impedance of the power amplifier needs to be reduced, i.e. the impedance of the second antenna needs to be reduced.
In some possible implementations of embodiments of the present application, the signal quality of the transmitted signal may be brought to the target signal quality by tuning the impedance of the tuner 27 corresponding to the antenna after antenna switching in step 104.
In some possible implementations of embodiments of the present application, it is possible that one tuning does not enable the signal quality of the transmitted signal to reach the target signal quality, and therefore, the forward power and the load reflected power of the power amplifier after each tuning can be detected by tuning multiple times and using the coupler 24, and thus, the determination is made based on the forward power and the load reflected powerThe impedance of the second antenna after each tuning is made to approach the load impedance of the power amplifier to Z optimm The signal quality of the transmitted signal is made to approach the target signal quality.
In some possible implementations of embodiments of the application, due to the limited tuning range of tuner 27, there is a load impedance Z that is unable to tune the impedance of the second antenna to a target signal quality for the signal quality of the transmitted signal optimm . Based on this, the method for improving the quality of the transmission signal provided by the embodiment of the application may further include: and under the condition that the signal quality of the transmitted signal cannot reach the target signal quality by tuning the impedance of the second antenna, adjusting the working parameter of the power amplifier into a first working parameter, wherein the target signal quality is the signal quality which can be reached by the maximum signal quality of the transmitted signal, and the first working parameter is the working parameter which can enable the signal quality of the transmitted signal to reach the maximum signal transmission quality corresponding to the current impedance of the second antenna.
It should be noted that there may be multiple sets of operating parameters (e.g., operating voltage, quiescent operating current (ICQ)) for the power amplifier, where each load impedance corresponds to a set of operating parameters that enable the signal quality of the transmitted signal to be maximally achieved at that load impedance. The power amplifier, when in operation, will invoke a set of operating parameters to operate.
In some possible implementations of the embodiments of the present application, the signal quality of the transmission signal may be affected by the working parameters of the power amplifier, based on which, for each Load impedance, different working parameters of the power amplifier may be traversed through Load-pull tests in advance, so as to obtain the working parameters that enable the signal quality of the transmission signal to reach the maximum signal transmission quality corresponding to each Load impedance, and further obtain the corresponding relation between each Load impedance and the working parameters of the power amplifier. Illustratively, the load impedance corresponds to the operating parameters of the power amplifier as shown in table 1.

After tuning the impedance of the second antenna a plurality of times, the impedance of the second antenna cannot be tuned any more due to the limitation of the tuning range of the tuner 27, and at this time, the operating parameters of the power amplifier are adjusted so that the signal quality of the transmission signal is optimized.
For example, when the impedance of the second antenna is adjusted to Load4 in table 1, the impedance of the second antenna cannot be tuned any more, and at this time, the operating Parameter of the power amplifier is adjusted to an operating Parameter2 corresponding to the Load impedance Load4, so as to optimize the signal quality of the transmission signal.
